Answer:
6 pints or 3 quarts
Explanation:
We can represent the actions onto the ice cream with mathematical operations. First, we can represent giving 1 quart away as subtraction:
14 pints - 1 quart
= 14 pints - 2 pints
= 12 pints
So after giving 1 quart to his neighbor, Jahlil has 13 pints left. Of these 13 pints, he uses half to make milkshakes. We can represent a half by dividing by 2:
12 pints / 2
= 6 pints
= 3 quarts
So, Jahlil used 6 pints or 3 quarts of ice cream to make the milkshakes.
